我正在寻找一种方法来创建XWalkWebResourceResponse.我的情况如下.

我正在创建自定义XWalkResourceClient客户端,它将拦截所有网络请求.所有应该被拦截的请求都会以抽象包装器的形式返回 – AppWebResourceResponse.

public final class CrossWebViewClient extends XWalkResourceClient {
    // other fields and constructor

    CrossWebResourceResponseMapper responseMapper;

    @Override
    public XWalkWebResourceResponse shouldInterceptLoadRequest(XWalkView view, XWalkWebResourceRequest request) {
        AppWebResourceRequest mappedRequest = requestMapper.toGenericRequest(request);
        AppWebResourceResponse interceptedResponse = requestInterceptor.shouldInterceptRequest(mappedRequest);
        if (interceptedResponse == null) {
            return super.shouldInterceptLoadRequest(view, request);
        }
        return responseMapper.toTargetResponse(interceptedResponse);
    }    
}

最后一步.
我必须将AppWebResourceResponse调整为XWalkWebResourceResponse,这是我遇到问题的地方.

public class CrossWebResourceResponseMapper implements AppWebResourceResponse.Mapper<XWalkWebResourceResponse>  {
    @Override
    public XWalkWebResourceResponse toTargetResponse(final AppWebResourceResponse appResponse) {
        String mimeType = appResponse.getMimeType();
        String encoding = appResponse.getEncoding();
        int statusCode = appResponse.getStatusCode();
        String reasonPhrase = appResponse.getReasonPhrase();
        Map<String, String> headers = appResponse.getResponseHeaders();
        InputStream data = appResponse.getData();


        // ??? how to create response object?
        XWalkWebResourceResponse response;

        response.setMimeType(mimeType);
        response.setEncoding(encoding);
        response.setStatusCodeAndReasonPhrase(statusCode, reasonPhrase);
        response.setResponseHeaders(headers);
        response.setData(data);
        return response;
    }
}

根据API有公共构造函数新的XWalkWebResourceResponse(桥)消耗桥对象,虽然我没有找到一种方法来检索特定的桥(org.xwalk.core.internal.XWalkWebResourceResponseBridge).

我在哪里可以检索XWalkWebResourceResponseBridge？

提前致谢.

2016年4月25日更新：

根据Xiaofeng,可以使用XWalkResourceClient对象创建XWalkWebResourceResponse对象.

public class XWalkWebResourceResponseMapper {
    public XWalkWebResourceResponse toTargetResponse(XWalkResourceClient client, AppWebResourceResponse appResponse) {
        String mimeType = appResponse.getMimeType();
        String encoding = appResponse.getEncoding();
        int statusCode = appResponse.getStatusCode();
        String reasonPhrase = appResponse.getReasonPhrase();
        Map<String, String> headers = appResponse.getResponseHeaders();
        InputStream data = appResponse.getData();

        return client.createXWalkWebResourceResponse(mimeType, encoding, data, statusCode, reasonPhrase, headers);
    }
}

public final class CrossWebViewClient extends XWalkResourceClient {
    @Override
    public XWalkWebResourceResponse shouldInterceptLoadRequest(XWalkView view, XWalkWebResourceRequest request) {
        AppWebResourceRequest mappedRequest = requestMapper.toGenericRequest(request);
        AppWebResourceResponse interceptedResponse = requestInterceptor.shouldInterceptRequest(mappedRequest);
        if (interceptedResponse == null) {
            return super.shouldInterceptLoadRequest(view, request);
        }
        return responseMapper.toTargetResponse(this, interceptedResponse);
    }
}

解决方法:

谢谢使用Crosswalk.

要创建XWalkWebResourceResponse,您应该在XWalkResourceClient中使用createXWalkWebResourceResponse,请参阅here.由于内部块问题,它不能使用通用构造函数来创建.

以下是有关如何使用它的示例：https://github.com/crosswalk-project/crosswalk/pull/3454/files

 class MyResourceClient extends XWalkResourceClientInternal {
 MyResourceClient(XWalkViewInternal view) {
     super(view);
 }
 @Override
 XWalkWebResourceResponseInternal shouldInterceptLoadRequest(XWalkViewInternal view,
         XWalkWebResourceRequestInternal request) {
     // Handle it here.
     // Use createXWalkWebResourceResponse instead of "new XWalkWebResourceResponse"
     // to create the response.
     // Similar with before, there are two function to use:
     // 1) createXWalkWebResourceResponse(String mimeType, String encoding, InputStream data)
     // 2) createXWalkWebResourceResponse(String mimeType, String encoding, InputStream data,
     //             int statusCode, String reasonPhrase, Map<String, String> responseHeaders)
     ...
 }

}

稍后您还可以在XWalkView API文档中看到这一点.
